Hello,

chain ramp plastic is brown or ivory, not green. This green rubber is coming from valve stem seals (4).

Don't know if there is enough room to change them when engine is in the car. You have to remove the camshafts and hydros to get to the valves. Than you'll need a special plier tool to press down the valves so you can remove the valve collect (1). Than you can remove the spring (3) to get to the valve stem seals. And than replace them.

Regards, Markus
